Hello,
Unfortunately, it seems as though the verification email for my preferred email address is getting stuck somewhere down the line. Every time I click ‘resend verification email’, nothing comes to the selected email’s inbox/spam box.
I’ve got the same problem, it might be the huge amount of verifications sent because of people participating the insider program, try agin tomorrow maybe
There is a pinned thread for this in the Insiders forum if you are still having trouble
